SULKY-PLO'W.

SPECIFICATION formingpart of Letters Patent No. 256,422, dated April 11,1882. Application filed March 9, i882. (ModcLl To all whom it mayconcern Be it known that we, MYRON G. WOOD, of Oburchs Corners, in thecounty of Hillsdale, and in the State of Michigan, and WALTER O. PRATT,of Hudson,Lenawee county, Michigan, have invented certain new and usefulImprovements in Sulky-Plows; and we do hereby declare that the followingis a full, clear, and exact description thereof, reference being bad tothe accompanyingdrawings, and to the letters of reference markedthereon, making a part of this specification..

This invention relates to certain improvements in sulky-plows; and ithas for its objects to provide improved mechanism whereby the plow maybe inserted in or withdrawn from the ground, the width of the furrowvaried within certainlimits at will, and the plow 'winged by the driverwith ease and convenience withoutleavinghis seat, as more fullyhereinafter specified. These objects we attain by the apparatus andmechanism illustrated in the accompanying drawings, in which- Figure 1represents a side elevation of the improved sulky-plow Fig. 2, a topview of the same, and Fig. 3 a rear view of the plow.

The letter A indicates a bent metallic axle,

' upon which are mounted the wheels B, one

- nuts at the end.

end of the axle being higher than the other to permit one wheel to runupon the surface of the field, while the other travels in the furrow-which itis forming. The upper horizontal portion of the bent axle isprovided with hangers 0, between which is pivoted a frame, D,

by means of a transverse bolt provided with E, by means of which thebolt may be adjusted vertically to vary'the height of the frame, as maybe required.

The letter F indicates the tongue or pole of the plow, which is rigidlyattached to the upper horizontal portion of the axle at one side. Tothis tongue, in front of the drivers seat, is bolted a ratchetedsegment, G, and pivoted an angle-lever, H, which is provided at itsupper end with a suitable handle, so located as to be under convenientcontrol of the driver. The lower end of said lever is loosely connectedhorizontal portion of the bent axle.

The hangers are each pro vided with two or more apertures or bearings,

with a link, I, hooked at its lower end to the forward end or theplow-beam K. To the fulcrum-pin of the angle-lever H is also pivoted acurved lever, L, .which is provided with a horizontal slotted head, M,adapted to play upon a bolt, N, passing through the slot and secured tothe lever H. The lower end of the said curved lever is provided with astirrup, P, by means of which it can .be-operated-by the foot ofthedriver, and the curved portion extends and is adapted to play betweenafriction-roller, R, and a pin, S, secured to a short hanger on theframe D, for the purpose more fully hereinafter described. The rearportion of the frame D has secured to it a segment, T, upon the ends ofwhich are secured and adapted to play the loops U on the upper ends ofthe links V, which are adjustably secured by means of the guides W andbolts X to the oblique arms of a transverse bar, Y, securely fastened tothe rear of the plow-beam, by

means of which the plowbeam is suspended ver has loosely connected to itthe rear end of a rod, 0, the forward end of which is pivoted to thelower end of a lever, D, fulcrumed to a ratcheted segment, E, securelyattached to a short beam, F, rigidly secured to the upper The said beamis also provided with aratchet-plate, G, and guard H, between which isadapted to play the upper end of an angle-lever, I, which is fulcrumedin a bearin g, K, secured to the lower horizontal portion of the bentaxle at one end. Thelower end of said leverhas loosely attached to itone end of a rod, L, which is connected to a plate, M, secured to theforward end of the plow-beam. The opposite end of said plate is securedto a brace-rod, N, which connects with the axle at P. The levers H and Dare provided with detents R S adapted to engage and be held by therespective ratchets before mentioned. The lever I is adapted to engagethe teeth of the ratchet-plate, being pressedagainst the edge of thesame by means of a spring, T, bearing against the guard beforementioned.

The various rigid parts of our improved plow may be secured together bymeans of suitable clips and bolts, or in any other convenient manner.

The operation of our invention is as follows: To elevate or depress theplow, the lever H is brought back or pressed forward by the driver. Theinitial movement of the lever operates the forward end of the plow-beam,so as to incline the pointof the plow properly to be withdrawn.

from or pressed into the ground, the bolt slipping in the slotted headof the curved lever, permitting it to remain inactive. The finalmovement of the lever H carries the bent lever in the proper directionto operate the frame 1) positively and elevate the plow or set it intothe ground, as may be required. When it is desired to wing the plow thelever D is turned forward or backward, causing the plow to incline inthe desired direction. In order to regulate the width of the furrow, thelever I is operated, moving the forward end of the plowbeani laterally,so as to present the plowshare S at a greater or less angle to the lineof travel, and cause itto cut to a greater or less width.

In the above we have described the segment at the rear of the frame ashaving loosely supported upon it the looped links connected with therear of the plow-beam; but it is evident that the segment may bearranged to slide, and the links may be rigidly attached to it and thesame object effected.

The play of the curved lever upon the upright lever permits a slightmovement to the plow beam and share when the share meets with anobstruction, so as to prevent the shock which would come upon the sharewhen suddenly and violently brought'against such 0bstruetion, thuspreventing the injury attendant upon such shock.

Having thus described our invention, what we claim, and desire to secureby Letters Patcut, is--- 1. In combination with the bent axle and thetongue or pole of a sulky-plow having a ratcheted segment, the angle-lever fulcrumed to the segment and loosely connected to the forwardpart of the plow-beam, the curved lever ful' crumed to said segment andprovided with a slotted head adapted to play upon a bolt upon theangle-lever, and the pivoted frame D, provided with a friction-rollerand pin between which the curved lever plays, substantially as and forthe purpose specified.

2. In combination with the frame D, pivoted to the bent axle, and thesegment T at the rear thereof. the plow-beam provided with the yoke U VY, the bell-crank, connecting-rods, and the lever I) for operating theplow to wing the same, substantially as and for the purposes set forth.

3. In combination with the bent axle and plow-beam, the an gle-lever I,fulorumed to the axle, the connecting-rods L N, and the beamclamp M,whereby the width of the furrow may be regulated, substantially asspecified.

In testimony whereof we affix our signatures, in presence of twowitnesses, this 4th day of March, 1882.
